Yes, that is what I'm thinking too.  I was unsure of one of the females, at first.  While I only have Black Australorps, of the parent stock, I have a hen that is pure Kirk Keen line, but the other hen is the result of outbreeding the Kirk Keen line with the Dan Castle line.  The rooster is from that pairing as well.  The resulting chicks all did well at the shows, however, there are subtle distinctions between the two lines. 
I put the daddy rooster over his offspring, for these.  While there is less distinction than before, the females that have more of the Kirk Keen line in them, are easier to distinguish as such, at an earlier age.  I know the outbred line is outstanding, but there is just something about the ones that have more of the Kirk Keen traits, that appeals more to me.  I don't exactly know why.
